Zhidan SUN

Zhidan SUN is an Associate Professor at the University of Technology of Troyes, France, affiliated with the Laboratory of Mechanical & Material Engineering (LASMIS). He has been serving in this position since September 2019, following his role as Assistant Professor from September 2013 to August 2019. His academic journey includes research and teaching positions at Université de Versailles Saint-Quentin-en-Yvelines, ISAE-ENSMA, and MINES ParisTech-CEMEF.

Dr. Sun's research focuses on mechanical properties of materials in relation to microstructural and environmental parameters. His work encompasses characterization of tensile and fatigue properties, analysis of damage and fracture mechanisms, and numerical modeling with finite element methods. Key research areas include time-dependent grain boundary embrittlement of copper alloys, multiscale modeling of hot tearing during solidification of metals, fatigue crack growth affected by gaseous hydrogen, cohesive zone method based thermo-mechanical fatigue models, and characterization and multiscale modeling of materials processed by Surface Mechanical Attrition Treatment (SMAT).

His recent publications demonstrate a consistent focus on surface treatment techniques, particularly SMAT and shot peening, and their effects on mechanical properties, fatigue behavior, and residual stress distribution. These works span from fundamental material characterization to advanced numerical modeling approaches, with applications in aerospace, biomedical, and electronic materials. The research shows a progression toward more sophisticated multiscale modeling and experimental validation techniques.

With 87 publications, 24,998 reads, and 1,307 citations according to ResearchGate, Dr. Sun has established himself as a significant contributor to the field of material mechanics and surface engineering. He serves as a Guest Editor for the journal Metals, reflecting his standing in the academic community.

Dr. Sun's research involves extensive collaboration with colleagues across multiple institutions, as evidenced by his co-authorship network. His work addresses critical challenges in material performance prediction and enhancement, particularly for components subjected to cyclic loading and demanding environmental conditions.
